BUTTON SETTlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 661,309, dated November6, 1900.

Application filed January 5, 1900. Serial No. 489. (N model.)

To all, whom it may concern:

Be it known that we, GEORGE W. GWINN and HENRY 0. SMITH, citizens of theUnited States, residing at Baltimore, in the State of hilaryland, haveinvented certain new and useful lm 'irovements in Button-Setting Machines, of which the following is a specifica- IlOn.

This invention relates to an improved machine for attaching buttons togarments by means of a staple or other similar fastener; and theinvention consists of a machine having substantially the parts andcombination of parts hereinafter particularly shown, described, andclaimed.

Referring to the drawings, Figure 1 is a side elevation of the completemachine. Fig. 2 is a view showing the opposite side of the chuck and armfrom that shown in Fig. 1. Fig. 3 is a vertical longitudinal section ofFig. 1, the magazine and lower part of the stand being broken away. Fig.4 is an inverted plan View of the arm and base-plate, showing theplunger and chuck in their normal positions. Fig. 5 is also an invertedplan view of the base-plate with the parts in the position they occupywhen the plunger makes its extreme traverse. Fig. 6 is a front elevationof the base-plate and chuck, the arm and chute being broken away. Fig. 7is a view, on an enlarged scale, of the chuck and mechanism forcontrolling the escape of the staples from the chute to the chuck. Fig.Sis a section on the line X X of Fig. 7.

Similar numerals refer to like and corresponding parts throughout theseveral views.

1 designates a stand to which is secured a base-plate 2, in which latterthe plunger 3 reciprocates. The plate 2 is secured to the stand 1 bymeans of bolts at and has an arm 5 projecting therefrom, which latter isprovided with a magnetized collar 6, to hold the metal button, and aclencher 7. The said clencher is on a plane with the plunger and servesto clench the staples around the bar of the buttons.

The plunger 3 is provided on its lower surface with a plate 8, which issecured thereto by means of the screw 9. This plate 8 has I two beveledfingers 10, the purpose of which will be presently pointed out. At thefront of the plunger is a chuck 11, which latter is provided with twojaws 12, pivoted thereto and having their front ends projecting upwardflush with the top of the chuck. The said chuck is secured to theplunger by means of the pin 13, which passes through the slot 14 in thechuck 11. The plunger, it will be seen, is free to move back and forthwithin the chuck for a limited distance without moving the latter. Thechuck is also provided with a screw or pin 15 to keep the jaws 12 intheir proper relative position when brought together. The jaws 12 areprovided with a spring 22 to keep them normally closed. The chuck 11 isprovided at the rear end with a shoulder 20, which abuts against the lug21 on the chute to limit the forward movement of the chuck and hold itwhile the jaws 12 are being forced apart by the plunger.

The machine is also provided with a magazine 16, having a slotted chute17, through which the staples 18 are conveyed to the chuck. The magazine16 is revolved by motion transmitted through the several levers and rodsto the rod 37, which operates the ratchet 24. As the magazine revolvesthe staples fall through the slots 25 and pass into the slotted chute17, where they are conveyed to the chuck 11. Near the lower end of thechute 17 is a pin 26, on which the staples rest. This pin 26 is held toits normal position across the slot by the spring 27. As the plunger 3makes its forward stroke the pin 13 comes in contact with the lower endof the lever 28, which latter moves forward, causing the beveled edge 29of the lever 28 to come under the head of the pin 26 and raise it upagainst the tension of the spring 27, thereby drawing the said pin 26from the slot and allowing a staplc to fall. The said lever 28 isreturned to its normal position by the spring 30. At the time the lever28 is returning to its normal position the lever 31, which is normallyheld under the head of the pin 32 by means of the pin 33, is released bythe spring 34, when the pin 33 moves forward with the chuck 11, therebyallowing the said pin 32 to be forced across the slot of the chute bythe spring 35 pressing on the head of the said pin 32. WVhen the lowerpin 26 is withdrawn from the chute, the upper pin 32 is forced acrossthe said slot, thus allowing but one staple to drop at one time.

The plunger is provided with lock-nuts 38 to determine its forwardmovement and an adjustable screw 39 to prevent the plunger coming backtoo far.

The operation of the machine is as follows: After the magazine andslotted chute have been filled with staples the button is placed againstthe magnetized collar 6, the bar of the button extending across theclencher 7. The garment is then held in position and the treadle 19 ispressed down, which imparts motion through the several levers and rodsto the plunger 3 and causes the latter to move forward. As the plunger 3makes its preliminary traverse the fingers 10 of the plate 8 come incontact with the rear ends of the jaws 12 and as the latter are pivotedto the chuck carries the chuck forward until the shoulder 20 comes incontact with the lug 21 n the ch ute. As the chuck cannot then move anyfarther forward, the plunger continues forward, (the pin 13 movingthrough the slot 14,) and the jaws 12 are forced apart by the beveledfingers 10, as shown in Fig. 5. The plunger continues out to its finaltraverse and carries with it a staple 18, one of which latter alwaysoccupies the position shown in Fig. 3. The legs of the staple straddlethe bar of the button (not shown) held by the magnetized collar 6 andare clenched around the said bar by the clencher 7. The button beingthus secured to the garment the treadle is released, and as the plungerbegins to move back to its normal position the jaws 12 will still remainopen until the rear ends thereof come in contact with the pin 23 on thestand 1, which will hold the said jaws until the plungerhas moved backfar enough for the fingers 10 to release the jaws, which latter willthen be closed by means of the spring 22. The plunger then continuesback to its normal position.

WVe claim 1. In a button-setting machine, the combination of achuck, 11,having two jaws, 12,
